Airtac LRM Miniature Linear Guide LRM12N1X395S10BPT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X395S10BPT is a miniature linear guide on a 12 mm stainless-steel rail with recirculating-ball carriage. It is the small end of the range, for light-duty precision positioning in a tight envelope — compact stages, small pick-and-place heads and inspection fixtures.

About the Airtac LRM Miniature Linear Guide LRM12N1X395S10BPT
This is LRM12N1X395S10BPT, a complete LRM miniature linear guide set: a stainless-steel rail 12 mm wide and 395 mm long carrying one standard-length recirculating-ball carriage. The trailing T marks bottom-mount fixing - the screw holes sit on the rail's base, so fasteners stay out of sight under the rail - and the P marks the precision accuracy grade, the tighter of the two LRM options.
Inside, ISO 3290 G10 Japanese balls recirculate in a carriage that a ball-retention design keeps from spilling during careful handling; the maker still cautions against angling it onto the rail or swapping it hastily, since balls can drop even so. A double-lip seal scrapes oil back and excludes dust, while an outer cover shields the seal strip from larger debris. Ambient temperature must stay at or below 80 C with peaks to 100 C. Load and moment ratings are not published for this series, so we confirm the figures for this exact model through the RFQ before you order.

Where the Airtac LRM Miniature Linear Guide LRM12N1X395S10BPT Is Used
Benchtop machine retrofit
Retrofitting an older benchtop tester? The bottom-mount rail bolts up from underneath, so the original top surface needs no new visible drilled holes.
Custom OEM dispensing stage
An OEM building a compact dispensing stage specifies the 395 mm length and precision grade P to hold a nozzle path consistent across production runs.
High-cycle scanner slide
A rapid optical scanner cycles a light sensor head continuously; keep the 100 km re-grease interval in mind, since a short fast stroke can reach it in a matter of weeks.
Is the Airtac LRM Miniature Linear Guide LRM12N1X395S10BPT the Right Guide?
With no published dynamic, static or moment ratings for LRM, anything beyond light-duty needs sizing elsewhere - LSH publishes per-carriage C, C0 and moment values you can check against, and LGC suits short travels where crossed-roller rigidity wins. Before ordering this set, tick off: complete set form, 12 mm rail width, standard carriage, one carriage, 395 mm rail length, light preload B, precision accuracy P and bottom-mount mounting. Rail lengths from 40 to 995 mm are stocked in 102 distinct cuts, so a 395 mm length is a standard offering rather than a special. If you later add a second carriage, put the datum face on the same side of the rail for better running accuracy, and confirm the load rating with us first - the RFQ takes a minute.
Quick checklist
- ✓ Complete set, carriage only, or rail only?
- ✓ Load and moment confirmed with us
- ✓ Travel length and mounting space
- ✓ Accuracy grade and preload
- ✓ Mounting surface ground or finish-milled
- ✓ Pairing code, if replacing a part
Installation & Maintenance Notes
- check Mounting surface must be ground or finish-milled.
- check Torque the rail screws per the recommended figures, in sequence.
- check Keep the mounting corner radius inside the stated R maximum.
- check Do not angle the carriage onto the rail; balls can drop out.
- check Drive the supplied bolt caps into the mounting holes.
- check Re-grease every 100 km of travel or every 3–6 months.
- check Installation by qualified personnel per AirTAC docs.
Airtac LRM Miniature Linear Guide LRM12N1X395S10BPT FAQ
Stainless-steel rail, 12 mm wide and 395 mm long; one standard carriage; preload B light; accuracy P precision; bottom-mount rail. Fixing torque for M3 screws is 196 N.cm into steel, 127 N.cm into cast iron and 98 N.cm into aluminium, and for M2 screws 58.8, 39.2 and 29.4 N.cm. The ambient limit is 80 C with 100 C transient peaks, and re-greasing falls due every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM, so we confirm them per model on request.
When the load is heavy, overhung or dynamic enough that you need published numbers to sign off a design. LRM publishes none, and we confirm ratings per model instead; the larger LSH series publishes per-carriage dynamic, static and moment ratings you can calculate with, and LGC covers short travels needing crossed-roller rigidity. If your payload or duty cycle has outgrown light-duty, send the figures with an RFQ and we will recommend staying with LRM or stepping up.
